well... you see, if you cut yourself in an area where a vein is you might see blood come out! inside one drop of blood are millions of DNA strands! Millions of years ago, there were mosquitos, just like today. they would bite a dinosaur and drink its blood. after that, the mosquito might land on a tree and get stuck in tree sap! Millions of years later the tree sap would become hard, just like a fossil, and turn into what we call 'amber'. the amber would get diged out of the ground. Then the blood inside of the preserved mosquito can be taken out and... Bingo! dino DNA!!! thanks to Ingen scientists, they fill in the missing gaps of the DNA with frog DNA and now we can create a baby dinosaur!
